Discussion :: Steam Nozzles and Turbines - Section 3 (Q.No.15)
| Tapan Majumder said: (Nov 28, 2013) | |
| Blade velocity = v(1)*cos(alpfa). v1 = steam velocity at the exit of the nozzle. v1 = 320/cos(30) = 640/(root3). |

| U/v = cos α for reaction turbine (parson). | |

| Explain the answer clearly. | |
| Rupesh said: (Dec 9, 2018) | |
| u/v=cos α so u has value 320; α= 30. 320/v= cos 30. V=640/√3. |

| Here it is said that exit velocity of rotor, not nozzle so Option B is correct. | |

| Stream velocity at exit of rotor =Vr (2) = V1 and vane angle at outlet = inlet nozzle angle according to conditions of 50% rxn turbine. | |
